Models Physical Model Used to show predictions, like storms around the world Conceptual Model A model that shows a thoery, like the big bang theory Mathematical Model A model that shows math, like a cirlce graph Scientific Method Step 1: Ask a Question Step 2:Research Topic Step 3: Make a Hypothesis Step 4: complete Experiment Step 5: Analyze the Experiment Step 6: Collect Data Step 7: Draw Conclusions Types of Energy: Kinetic: energy of movement Potential Energy: energy of position Mechanical: energy of motion and position Sound: energy of vibrations Electrical: Energy of moving elctrons Chemical: that part of the energy in a substance that can be released by a chemical reaction Nuclear Energy: the energy released by a nuclear reaction Radiant Energy: energy that is transmitted in the form of (electromagnetic) radiation matter Solid: particles are vibrating in place, definite shape and volume Liquid: particles move freely; definite volume, indefinite shape
Gas: Particles move freely and fast; no definite shape or volume Interactions of Waves: Refreaction: When a wave enter a new medium at an angle, one side of wave enters the wave before the rest of it. Diffraction: when a wave curves or bends around a barrier Reflection: when a waves bends and show the same image
